Sadly, no, not in 2003/XP. Windows Vista adds group policy support for this. I would suggest your best option would be to create a .REG file modifying the default user (and possibly the current user) - the default user is where the default power settings are which the current user can then customize for themselves (had a b*tch of a time figuring this out to keep machines from going to sleep when we needed them on and available for Remote Desktop.
